PAUL LUX, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE lLUX CLOCK MANU-FACTURING COMPANY INC., 03 WATERBURY, CONNECTICUT, A CORPORATION OFCONNECTICUT.

ALARM-CLOCK.

Specification of Letters Patent.

Application filed April 19, 1921. Serial No. 462,551.

To all whom it may concern 7 Be it known that I, PAUL LUX a citizen ofthe United States, residing at Waterbury, in the county of New Haven andState of Connecticut, have invented certain new and useful Improvementsin Alarm-Clocks, of which the following is a specification, referencebeing had therein to the accompanying drawing. I a v This inventionrelates to certain new and useful improvements in alarm clocks and moreparticularly to the bell arrangement forthe same, the object being toprovide a concealed bell alarm employing a fiat gong in connection withavnovel construction of hammer and means for operating the same i: f theclock so that the head will strike against the metal gong plate whichisdisposed between theclock movement and the back of the case.

Another and further object of the invention is to provide a novel formof support for the hammer wire in the form of a bracket in which thehammer wire is loosely mounted, one end of the same being provided witha rightangled bend working in an opening formed in the hammer taillever, the size of the opening of which controls theendwise movement ofthe hammer wire in the bracket 7 which provides a very simple and cheapconstruction of alarm and one which is very efiicient ineuse.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings,

Figure 1 is a rear elevation of an alarm constructed in accordance withmy invention showing the gong plate in dotted lines;

Fig. 2 is a top plan view; s

Fig. 3 is a detail perspective view of the hammer wire bracket, hammerwire and hammer tail lever detached; and

Fig. 4 is a detail top plan view of a slightly modified form of mountingthe gong plate.

In carrying out my invention I employa front frame 1, a back frame 2connected together by the usual pillars 3 and having an alarm mainspring 4 and a winding key 5.

The frame is provided with the'usual alarm maln wheel 6 which mesheswith a pinion 7 carried by arbor 8, said arbor having an alarm crownwheel 9 which is engaged by an alarm verge 10 in the usual manner andwhile I have only shown certain elements of the alarm clock, it is ofcourse, understood that inuse clocks constructed as now generally in useare'employed having the regular time control mechanism so as to causethe alarm main wheel to rotate.

The back 11 of the case carries bell posts 12 on which is mounted a flatgong plate 13 disposed between the back, of the case and the clockworkand adapted to be engaged by the hammer as will be later'described.

Secured to the back frame 2 is a hammer wire bracket 14: in which isloosely mounted a hammer wire 15 having a head 16 capable of engagingthe gong plate 13. The other end of the hammer wire 15 is bent at rightangles as shown at 17 forming an angled end which extends through anopening 18 formed in a hammer lever 19 carried by the the alarm verge,the endwise motion of the hammer tail wire being controlled by theopening in the hammer lever and as the verge imparts an up and downmovement to the hammer lever, the hammer wire 15 is oscillated so as tobring the hammer head intermittently into engagement with the gong plate13 to sound an alarm.

It will be seen that by this construction a very novel form of hammerand hammer tail is provided in connection with a novel form of hammertail lever which allows the parts to be readily assembled in a veryeconomical way.

In the modification shown in Fig. 4 the back frame 2 carries bell posts20 for supporting the fiat gong plate 21 in such a position that it canbe engaged by the hammer and I do not wish to limit myself to theparticular manner of mounting the fiat gong plate as I am aware that thesame can be mounted in various ways without de arting from the spirit ofmy invention. 11 both forms I have shown the same disposed between theclock movement and the back of the case and when arranged 111 thismanner it will be in position to be engaged by the hammer head of thealarm mechanism and it will be seen that by this construction I haveprovided a concealed bell alarm for alarm clocks composed of a very fewparts so arranged and assembled that a very ethcient and economicalconstruction is provided.

In the application of my improved construction of alarm for clocks, theback or use is perforated in order to allow the sound waves to pass outof the case and I do not wish to limit myself to the use of my improvedconstruction of alarm to any particular construction of case as I amaware that *arious constructions can be used without departing from thespirit of my invention.

What I claim is 1. The combination with an alarm clock having an alarmmain wheel and an alarm crown wheel for actuating the alarm verge, agong disposed between said clock work and the back of the case a hammerwire carrying a hammer said hammer wire having an angled tail and ahammer tail-lever carried by said alarm verge having an opening toreceive the angled hammer tail for causing the hammer to be oscillated.

2. An alarm clock having a flat gong plate disposed between the clockwork and the back of the case and a hammer arranged to engage said gongplate.

3. An alarm clock having a gong disposed between the clock work and theback of the case and a hammer wire havin a head at one end an a hammertail at the other end provided with a horizontal motion at right anglesto the back of the clock, said hammer tail being actuated by a hammertail lever for causing the hammer head to be intermittently brought intoengagement with the flat gong plate.

An alarm clock having a frame, a bracket carried by said frame, a hammerwire loosely mounted in said bracket provieed with a hammer head at oneend and a hammer tail at the other end and a l1ammer tail lever providedwith an opening arranged to receive the hammer tail wire for causing thehammer head to move at right angles to the back of the clock and a gongdisposed parallel with the back frame of the clock adapted to be engagedby said hammer head.

5. The combination with an alarm clock having the usual time controlmechanism including an alarm verge, a lever carried by said alarm vergeprovided with an opening, a bracket having a hammer wire loosely mountedtherein provided with an angled end working in said opening, a hammer atthe opposite end of said hammer wire and a plate disposed to be engagedby said hammer head.

6. in alarm clock comprising a frame ada; ted to be inelosed in a case,a gong disposed between the back of said case and said frame, said framecontaining time control mechanism includiman alarm verge, a bra ketcarried by said frame, a hammer wire mounted in said bracket having ahead at one end and an angled portion at its other end and a hammer taillever carried by said verge provided with an opening to receive theangled end of said hammer wire for causing said hammer to move at rightangles to the back of the clock and engage the metal gong plate.

In testimony whereof I hereunto aflix my signature.

PAUL LUX.
